PATENT 4` OFFICE l PENNSYLVANIA WHoRL Application filed April 18,

My invention relates to whorls for spinning and twisting machines andhas for one of its objects the provision of a whorl of improvedconstruction which enables such devices to withstand successfully therough usage to which whorls are subjected and a construction in whichthe cost of manufacture is materially reduced.

In spinning and twisting machines the bobbin is frictionally held inplace on the tapered spindle of the whorl and when it is desired toremove the bobbin from the spindle it becomes necessary oftentimes tolstrike the lower end of the bobbin with axmallet or other instrument inorder to loosen they bobbin and enable it to be removed.

The whorl is held in place in its bearings by a latch and when strikingthe bobbin unless care is exercised in this operation the flange of thewhorl will be driven against the latchV and chipped and thereby rendereduseless.

My invention provides a construction wherein the likelihood of chipping,of theV flange of the whorl is reduced to a minimum and wherein should.the Harige be chipped it may readily be removed and be replaced by a newflange instead of requiring replacement of the whole whorl as is nownecessary.

In the drawings wherein I have illustrated embodiments of my invention,

F 1 is a sectional elevation of one form of my improved whorl;

Fig. 2 is a sectional elevational view of the i whorl pulley beforeassembly; and

Fig. 3 is a sectional elevational view of a whorl pulley of modifiedconstruction.

Referringto the drawings in detail and first of all to Figs. 1 and 2, ldesignates a whorl spindle rotatable vertically in a fixed bearing 2.This bearing is providedwith a lateral extension or bracket 3 carrying apivoted latch arm 4 provided for latching the whorl in its bearing.

5 designates the whorl pulley which is made Vfrom bar stock ofsubstantially the Y same diameter as the desired finishedbody diametertherebyreducing the. cost of finishing to a minimum. The lower end ofthe. whorl body 6 is threaded as shown at 7 so as 1930. Serin No.445,269.

to receive an internally threaded removable flange ring 7 v .The bodyportion 6of the whorl pulley is straight sided and is boredlongitudinally for pai-tof its length as shown at 8 to receive l'extension 9 of the bearing 2,'the remainder of the bodyportionbeing'providedv with a f reduced taperedlongitudinal bore 10 to receive thespindle 1, which from the pointy 11 to the upper end rkof the spindle istapered so as *to frictionally hold the pulley thereto to4 provide adrive for the'spindle, and to frictionally hold the bobbin 12 on'thespindle for rotating therewith.

In operation a beltengages the bodyfportion 6 of the whorl pulley torotate the whorl and the bobbin. y i In removing the empt bobbin fromthetapering spindle lj the bobb to yhave become stuck on the spindle inwhich event it may be given a sharp blow with a mallet vor other`suitableinstrument so as to free it fro-1n 'the spindle. In striking'the bobbin the whorl may moveupwardly so that theliange ring 7 vstrikesthelatch L.twith a quick impact. :In previous constructions the whorlpulleys have been one piece cast iron structures -and underthe'conditions just outin may' be found lined the flange-ring aften ischipped and v the whorl thereby rendered useless, not only causingshutdown but necessitating substitution of a new whorl. By myconstruction, however, while chipping of the flange is a very remotepossibility, shouldl the flange ring 7 become chipped itjisa simplematter to remove'the ring `andto replace it with a new one.

It will be seen, therefore, from the foregoing that my improvedconstruction provides a whorl, the body of which is made from bar stocksubstantially the same diameter as the required finished diameter with aflange of largerV diameter than the b dy removably secured thereto.

In Fig.: 3 I have provided a construction similar to that just describedexcept in that the lower end of the body portion 6 which receives theflange ring 7 f is spun over so as to hold the flange ring in place whenassembled.

By constructing the whorl pulley iny two pieces which are removablysecured to each other and by employing cold rolled steel, for example,in my construction, not only do I effect a saving in cost of manufacturebut I effect a saving to the consumer in that When the Whorl flange isbroken or chipped the same may be readily replaced Without requiring himto go to the expense of replacing the entire Whorl pulley.

'1. A 'Whorl for spindles comprising an elongated cylindrical bodyportion, the upper end of the body portion being bored for the receptionof a spindle, the remainder of 15 the body portion being boredlongitudinally tofreceive a spindle bea-ring, and a flange for the bodyportion of greater outside diameter than .the outside diameter of thebody `portion and removably secured to the exterior of'tlie lower end ofthe body portion.

2. A spindle Whorl comprising an elongated cylindrical body portion ofround bar stool; of substantially the same diameter as the finished bodydiameter, lsaid body por tion being bored `at its upper end to providefor the reception of a spindle, the remainder ofthe vbody portion of theWhorl being bored longitudinally Yto freely receive a spindle bearing,and a'flange ring of larger outside v diameter than the body portion ofthe Whorl removably carried on the outside of the lower end of 'theWhorl. I

.3. A spindle Whorl comprising a cylindrical"elongatedbody portion boredat its upper end to receive a spindle, the remainder ofthe body lortionof the Whorl being bored longitudinal Ito freely receive a spindlebearing and a ange ring of larger outside diameter than the bodyportion, threaded 10 upon the lower-end of the said body portion.
